Construction method for ecologically protecting expansive soil slope by combining phosphogypsum with microbial mineralization
The present invention provides a construction method for ecologically protecting an expansive soil slope by combining phosphogypsum with microbial mineralization. The method includes: (1) placing Bacillus pasteurii in a culture medium to prepare a microbial solution, and mixing urea, calcium chloride and water to prepare a cementing solution; (2) preparing a mixture with phosphogypsum fly ash and soil; mixing the mixture, the microbial solution and water well, and adding the cementing solution and water to prepare an improving mixture slurry; and (3) spraying the improving mixture slurry to a face of the slope by wet spraying, and covering with a non-woven fabric by tying and fixing.
